The Douglas A-26 Invader () was a United States twin-engined light attack bomber built by the Douglas Aircraft Co. during World War II that also saw service during several of the Cold War's major conflicts. A limited number of highly modified aircraft (designation A-26 restored) served in combat until 1969.

The A-26 was an unusual design for an attack bomber of the early 1940s period, as it was designed as a single-pilot aircraft (sharing this characteristic with the RAF's de Havilland Mosquito, among others). The aircraft was designed by Edward Heinemann, Robert Donovan and Ted R. Smith.

The plane was re-designated from A-26 to B-26 in 1946, and this has led to popular confusion with the Martin B-26; Although both types used the R-2800 engine, they are completely different designs.

Nose Configurations of the Douglas A-26 "Invader"

The A-26 was originally built in two different configurations. The A-26B had a "solid" nose, which normally housed six (or later eight) .50 caliber machine guns, officially termed the "all-purpose nose", later commonly known as the "six-gun nose" or "eight-gun nose". The A-26C's "glass" nose, officially termed the "Bombardier nose", contained a Norden bombsight for medium altitude precision bombing. After about 1,570 production aircraft, three guns were installed in each wing, coinciding with the introduction of the "eight-gun nose" for A-26Bs, giving some configurations as many as fourteen (14) 50 caliber machine guns

Alongside the pilot in an A-26B, a crew member typically served as navigator and gun loader for the pilot-operated nose guns. In an A-26C, that crew member served as navigator and bombardier, and relocated to the nose section for the bombing phase of an operation. The rear gunner had a separate compartment where he operated the remotely-controlled dorsal and ventral gun turrets.
